TRANSLATE_BUS_ADDRESS callback function

Description

The TranslateBusAddress routine translates addresses on the parent bus to logical addresses.

Parameters

Context [in]

A pointer to interface-specific context information. The caller passes the value that is passed as the Context member of the BUS_INTERFACE_STANDARD structure for the interface.

BusAddress [in]

The bus-relative address to be translated.

Length [in]

The length, in bytes, of the input memory that BusAddress points to.

AddressSpace [in, out]

On input, the address space in which the device's hardware address resides. A value of 0x0 signifies memory space, and a value of 0x1 signifies port I/O space. On output, AddressSpace indicates the address space in which the TranslatedAddress resides.

TranslatedAddress [out]

The translated (logical) address that corresponds to the bus-relative address that the caller provides in BusAddress.

Return value

The TranslateBusAddress routine returns TRUE if the translation operation succeeded and FALSE otherwise.
